HEEL HOLDER.

Application led April 2, 1925,. Serial No. 20,211.

This invention relates to heel holders and particularly to heel holders of the type with which heel attaching machines are equipped fory holding and locating a heel or parts of a heel in position to be attached to a shoe. n

The object of the invention is to improve t-he construction of heel holders, with a View to increasing the accuracy of the location of the heel or heel parts,the range and variety of work which can be handled, and the ease and speed with which ychanges to accommodate heels of different sizes and shapes may be made.

The illustrative device herein shown is particularly designed to deal with two-part heels, one example of which is a heel .comprising a rigid base section and a rubber top section, commonly called a rubber heel. The utility of the invention, however, is not limited to two-part heels inasmuch as it will rbe apparent to those skilled in the art that some of its features are equally applicable to a holder for a unitary heel or a single heel sect-ion.

In attaching a rubber heel, or heel top section, in a heeling machine, where the heel is liable to be subjected to a considerable degree of pressure, it is desirable that the heel be held rigidly immovablein a holder or form which contines the heel around its entire periphery and which has a depth nearly equal to the height of the rubber heel, to prevent distortion of the heel by the pressure and .movement of the nail holes in the heel out of register with the holes in the nailing die of the heeling machine by which the attaching nails are driven. It is customary to provide a so-called ring or fixed form, for each size, shape and thickness of rubber heel to be attached, these rings or forms being so mounted in the heel attaching machine that they may be readily inter-y changed when it is necessary to change from operation upon one size of heel to another. lVhen the sections of a two-part heel are assembled and secured together before they are brought to the heeling machine as, for example, when a rubber heel and a leather heel base are preliminarily assembled and rsecured together by cement o r fastenings of some kind, the heel form of the type referred to constitutes a sufficient holder for the entire heel but if the two sections of the heel are separate' and unattached When placed in the heeling machine it is necessary to provide c means for holding the base section as Well as the top section. This has also been accomplished by making the heel form of ysufficient depth and so shaping the walls of the cavit-y in it that virtually two cavities are provided, one for the top section and another for the base.

It often occurs, however, that it is desired to use bases of different sizes or shapes with the same size and shape of top section and the provision of a sufficient number of solid forms to cover all the combinations which might occur would not only be prohibitively expensive but the forms themselves would occupy an unreasonable amount of space in the shoe factory. An important feature of the present invention accordingly consists in a heel holder in which provisionis made for a fixed form or ring to hold one heel part and a holder is provided for the other heel part which holder is readily adjustable to accommodate and properly locate heel sections of all sizes and shapes within reasonable limits,

- Rubber heels of different heights normally require rings or forms of different depths or thicknesses and a further useful feature of the invention consists in the provision of blank edge engaging members at least one of which is adjustable in the direction of the height of the blank. In the specific embodiment of the invention herein illustrated and described, this feature is embodied in a base holder which is adjustable heightwise land may therefore readily be so disposed as to engage properly the edges of a heel base, regardless ofthe thickness or height of the heel top section upon which it is placed.

In accordance with the invention adjustments are vfurther provided whereby the location of the base longitudinally with respect to the top section or rubber heel may be readily changed to suit the requirements of the work in hand and this adjustment is preferably independent of the heightwise adjustment previously referred to.

These and other features of the invention will best be understood and appreciated by reading the following detailed ydescription in connection with the accompanying drawings illustrating one embodiment thereof but it should be understood that various features of the invention might be embodied in other specilic forms or" construction without departing from its spirit and intent.

In the drawings,

Fig. l is a plan view of a heel holder embodying the invention;

Fig. 2 is a vertical longitudinal section on the line 2 2 ot Fig. l; and

Fig. 3 is a transverse section on the line SW3 ot l.

The holder herein shown is designed to be mounted upon a heeling machine in th same manner as the heel holder shown in my prior Patent llo. 1,365,802, J an. 18, l92l, and, as shown, may indeed be substituted bodily for the holder shown in the said )atent, to which reference may be had 'for cetails of its mounting and relationv to the other operatingk parts of the heeling machine.

Referring now to the dray"ings, lli and 18 indicate respectively the nailing die supporting member and the nailing die of a heeling machine and 2d indicates a stationary horizontal guide bar upon which the entire heel holder is supported and guided for movement by a guide slot G8 (Fig. cooperating with a stationary roll at the front ot 'the nailing die supporting member. These par'ts'all correspond to parts bearing the same reference numerals in the patent above referred to, as do the latch frm 64 and latch shalt 54 whoseV function is t lly described in said patent.

The sliding form car i r comprises a casting l which is provided with 'guides l2 in which may be removably secured a heel ring or form ld having a cavity shaped to the rubber heel to be attached. in interchangeable series of these forms is provided to accommodate all the dilterent sizes a shapes of heels to be handled. secured position in the carrier l0 by a pin 20 which is normally held in securing position by a spring 22 but which may be readily withdrawn to permit the changing olf forms. The end ol' the pin 20 is tapered as shown at 25 so that the form will always be located in the same position in the holder regardless ot wear upon the parts.

Superposed upon the form ld, which constitutes a lined holder for a rubber heel or heel top section, is an adjustable holder for the base decl: of a heel which will now be described in detail. A pair of lingers 28, shaped to engage the edges ot the blanlr at jacent to its breast corners, are pivoted to swing upon bolts 3() and are geared together as shown at 32 for equal and opposite movement to ensure that the blank shall be centered transversely. One et the lingers 28 is provided with a. laterally extending arm 3d to which is pivotally connected a rod 8G having' threaded upon its outer end an adjusting nut 38. The rod 36 is surrounded by a compression spring d0 of which one end The torni is bears against the arm 84 and the other end against a bracket d2, causing the lingers 28 normally to move toward each other to a limit determined by the adjustment of the nut 88.

The braclret 4t2 is integral with a carrier el in which the pivotbolts are secured. rlhe carrier ed, with the swinging lingers 28 carried thereby, is pivotally movable about the horizontal axis of a pin or rod LlG secured in lugs 48 formed on a slide 50 guided l'or rectilinear adjustment forwardly and rearwardly in suitable ways in the casting l0. This adjustment is el'lected by a screw 52 threaded into the casting l0 and having a manually operable adjusting knob 5G between which and a collar 58 is located a projection 60 depending Jfrom the slide 50.

The position of the carrier #le and the ngers 28, considerer vertically, is determined by an adjusting screw G2 threaded through the end ot the carrier and bearing upon the toj of the slide 50 and a spring 6G (Fig. 2) which tenes to elevate the lfront end ot the carrier and the lingers 28.

From the foregoing it will be understood that the blank edge engaging fingers 28 are adjustable forwardly and rearwardly with respect tothe cavity in the heel form ld by means et the screw 52 and are adjustable heightwise, both bodily and in relation the storm let, by means oi the screw 62.

The heel base, which is indicated in the drawings by the numeral 69, is additionally held and located by a l'orlred rear ZO which is carried by an approximately horizontal stem 72 slidable forwardly and rearvardly of trie holder in an adjustable bushing 7d and surrounded by a compression spring 76 which tends to move the rear gage Tf forward. The bushing 7d is threaded neon a. transverse horizontal axis in lugs 8O Legra with a bracket 82 which, in turn,

integral with the casting l0. rEhe position of the rocker member 78 and, consequently, ot the rear gage 7G, in a. vertical sense, is determined by adjustment of a screw 8d threaded through the bracket- Q2 against which screw the forward end olf the rocker member 78 is held by a spring 86 (Fig. 2).

It willvbe understood that. the rear gage is really mounted in the bushing 74, being yieldable rearwardly with respect to its mounting by reason of the spring 76, and that the gage is adjustable forwardly and rearwardly with respect to the openingin the heel l'orm le' by adjust-ment olf the bushing in the rocher member 78. Furthermore, heightwise adjustmentof the rear gage 70 is effected by turning the screw 8d to the desired point.

By proper adjustment ot the transverse space between the lingers 28 and the longitudinal position of the rear gage 7() with respect to said fingers, the base holder may be made to accommodate a heel section of any size or shape and by proper adjustment ot both the fingers 28 and the rear gage 70 longitudinally of the holder the base section may be positioned as desired in relation to the rubber heel in the form let. Furthermore, heiglitwise adjustment of both the lingers 28 and the rear gage 70 may be readily eiliected to cause them to engage the edges ot' a heel base section at a height to hold it most advantageously and to accommodate heel forms 14 of different thicknesses which may be required :tor rubber heels of diiierent heights.y

Having described the invention, what is claimed as new and desired to be secured by Letters Patent is:

l. A holder for multi-section heels having, in combination, a holder rfor one heel section, a separate holder for another heel section superposed uponfthe first, and means for eftecting relative adjustment of said holders in the direction of the height of the heel.

2. A holder for two-part heels having, in combination, a holder of fixed size -for positioning and holding the top deckot a heel by engagement with itsl edges, and an independent holder adjustable in size for the base deck of the heel, one ot said holders being superposed upon the other.

A holder tor two-part heels having, in combination, a holder of fixed size it'or positioning and holding one heel part by engagement with its edges, and an independent holder adjustable in size for the other heel part, one of said holders being superposed upon the other.

4. A holder for holding two parts of a heel in horizontal positions and superposed arrangement having, in combination, a stationary holder for positioning and holding one of the heel parts by engagement with its edges and a separate holder for the other heel part which is bodily adjustable horizontally in relation to the first-named holder to vary the relation between the two heel parts.

5. .A holder for holding two parts of a heel in horizontal positions and superposed arrangement having, in combination, a holder for positioning and holding one heel part by engagement with its edges and a separate holder for they other heel part which is bodily adjustable heightwise in relation to the first-named holder to accommodate heel parts ot' different heights.

6. A holder for holding two parts of a heel in horizontal positions and superposed arrangement having, in combination, a holder for positioning' and holding one heel part by engagement with its edges, and a separate holder for the other heel part which is bodily adjustable both heightwise and horizontally in relation to the first-named holder to vary the position of one heel part upon the other and accommodate heel parts of diiferent heights.

7. A holder for separate parts of two-part. heels having separate breast engaging members for the two heel parts, said members being relatively movable toward and from each other in the direction of their height.

8. A holder for-separate parts of twopart heels having a breast gage for one of the heel parts and separate breast engaging members for the other heel part, said members being movable toward and from each other and toward and from said gage in the direction of its height. n

9. A heel blank holder having a breast edge engaging member and a rear gage relatively movable toward each other to hold a heel. blank by its edges, both said member and said gage being adjustable heightwise ot the blank independently of each other.

In testimony whereof I have signed my name to this specication.
